Will a 1994 Jeep grand front axle with v8 fit 1993 straight 6 and both 4x4?

No, a 1994 Jeep Grand Cherokee front axle with a V8 will almost certainly not fit a 1993 Jeep Grand Cherokee with a straight-6, even if both are 4x4. While both are Grand Cherokees and 4x4, the V8 models often had different axles (generally Dana 44a) with different widths, gear ratios, and potentially different mounting points compared to the straight-6 models (often Dana 30).

Even if the axle *seems* to bolt up, the differences in width could lead to serious drivetrain issues and binding, potentially causing damage to the axles, transfer case, or other components. You'd likely need to modify the frame, which is not recommended for safety reasons.

Always check the specific axle codes (found on the axle housing itself) for both vehicles to confirm compatibility. Even with the same codes, there's still a risk of incompatibility due to variations within model years.
